The shown diagram is a fundamental and simpliﬁed example and

does not contain all components that are necessary in a system.

If the system you are about to install diﬀers from the shown

diagram of a standard heating system, feel free to sketch an

outline for comparison. Adaptation of systems, see section 10.

Sketch your application

The ECL Comfort controller series is designed for a wide range

of heating, domestic hot-water (DHW) and cooling systems

with diﬀerent conﬁgurations and capacities.

If your system diﬀers from the diagrams shown in section

10, you may want to make a sketch of the system about to

be installed. This makes it easier to use the Installer’s Guide,

which will guide you step-by-step from installation to ﬁnal

adjustments before the end-user takes over.

The controller is pre-programmed with factory settings that are

shown in the relevant sections of this guide.

However, you might come across some settings that are not listed

in this instruction. These settings could be related either to recent

updates or the use of optional modules (which are described in

the instructions in question).

How to use this guide

This guide is divided into two parts:

• User’s Guide: Yellow sections 1-7

• Installer's Guide: Grey sections 10 and onwards

The application L05 is very ﬂexible. These are the basic principles:

Heating:

Typically, the ﬂow temperature at S5 is adjusted according to

your requirements. The ﬂow temperature sensor (S5) is the most

important sensor. The desired ﬂow temperature at S5 is calculated

in the ECL controller, based on the outdoor temperature (S1).

The lower the outdoor temperature, the higher the desired

ﬂow temperature. The heat pump is switched ON when the

ﬂow temperature is lower than the desired ﬂow temperature.

A switching diﬀerence (line C) determines the action. The heat

pump is switched OFF when the ﬂow temperature is higher

than the desired ﬂow temperature or the max. limitation value

for the return temperature. If the measured room temperature

does not equal the desired room temperature, the desired ﬂow

temperature can be adjusted. The circulation pump, P1, is ON

when the desired ﬂow temperature is higher than 20 °C or the

outdoor temperature is lower than 2 °C.

The mixing circuit is used for a more eﬃcient distribution of the

heating: The ﬂow temperature sensor (S3) is the most important

sensor in the mixing circuit. The motorized control valve (M1) is

opened gradually when the ﬂow temperature at S3 is lower than

the desired ﬂow temperature and vice versa. The value of this

desired temperature inﬂuences the temperature in the heat pump

circuit.

DHW:

If the measured DHW temperature is lower than the desired DHW

temperature (a switching diﬀerence determines the action), the

change-over valve / DHW-pump is activated and the heat pump is

switched ON in order to heat the DHW. If the return temperature

rises above the accepted level, the heat pump is switched OFF and

stage 2 is switched ON.

Identifying the system type

10a

The ECL Comfort controller is a universal controller that can

be used for various systems. Based on the shown standard

systems, it is possible to conﬁgure additional systems.

In this section you ﬁnd the most frequently used systems. If

your system is not quite as shown below, ﬁnd the diagram

which has the best resemblance with your system and make

your own combinations.

The functions can only be realized with ECL Comfort 301 and as of

controller version 2.00.
